Then you must not know how to select a power supply. My ENTIRE system with a GTX 980, a 750Ti PhysX card, and a 4770k could run off that power supply he chose. My system draws around 400 watts from the wall under load, and everything in my machine is overclocked, even the RAM. Where the power supply matters is on the 12v rail. Can the PSU he selected supply enough AMPS to power that card, while keeping the entire system fed? Yes, with 46A on the 12v rail, that corsair can. This card needs 21 A. I like to play it safe with THAT number, give it about 33 percent and round up. So 30A under unusual circumstances, such as if the card were to short under full load. This still leaves a difference of around 16 amps to spare, so if the power supply falls short of its advertised ratings by a few amps(which occasionally happens, not so much with corsair) you're still completely safe. We're still within the threshold of the ONLY number that truly matters.
He could run his ENTIRE system off of a seasonic S12 520W Power supply, safely with never one hiccup, I guaran-damn-tee it.
And in all honesty, AMD CPU's have better multithreaded optimization than intels do. They just don't have the raw clock-for-clock power that Intels do, and they suffer even more for that because everything nowadays is poorly optimized for multithreading anyways. Thus, they always fall behind in benchmarks, especially in single-threaded benches. I've built a ton of AMD-based computers. Unless he is doing heavy compute threads, in normal everyday usage you'd never know whats under the hood, especially during gaming. Every processor gets hot, ESPECIALLY the haswell processors from intel. No real benefit on either side there.
